A woman pleaded not guilty Tuesday to a felony charge of stalking Hall of Fame announcer Bob Uecker. An attorney for Ann Ladd, 45, entered the plea at a preliminary hearing in Milwaukee County Circuit Court. Ladd, of Prospect Heights, Ill., waived her right to give testimony at the hearing, said her lawyer, Steve Kohn. Trial is scheduled to start July 31. If convicted, Ladd could face up to 3 1/2 years in prison and a $25,000 fine.
